Hey I hate op too.....What we do (we being my gold rank brother) is people spam opopopopopopopopopopop in chat then he says ok its gonna be op tri hearts!
Then at the last second after its says 1... he selects hardcore single hearts. When people start to complain and leave he just says" whoops hit the wrong one"
I would support this idea. For some who don't like op (*cough* @QuackoNumeroUno *cough*) you couldn't leave the lobby when you see a rank join.
